It is my understanding that wet plate and dry plate have similar approximate speeds- around 1 ASA. I also understand that wet plate needs light that is rich in UV, and dry plate being orthochromatic is also biased in the color spectrum. This being said, what are good light sources other than full sunlight, and how much of it do I need to get 1 second or less exposures? I currently have some 750 ws studio strobes, and I know at full power, I'd be lucky to hit f4 at five feet if I assume ASA 1 for my film speed. F4 is not enough DOF for a portrait on 5x7 or full-plate. Any suggestions? Can I do it with enough hotlights? What kind of strobe power do I need, and will they put out enough of the right kind of light? If fluorescents, what kind of total wattage do I need?
